I’ve been wondering for a very long time if using a teleconverter, moreover a 2x one, was worth it or not. I’ve heard a lot on forums that I would lose light, the aperture is reduced 2x (f/2.8 becomes f/5.6) that it is not sharp at all and that I would even lose autofocus. That made me doubt a lot even if it is not that expensive, but still, from $120 to $180 on average, that is always money coming out of you wallet that would be lost in the end if this is really bad!

I use this Sigma 150mm f2.8 APO macro lens for all my macro work that is very good but also big and heavy. I wanted to have this extra reach to do some wildlife photography without adding the bulk and weight to my backpack and without paying $1500-$2000 for a 300mm lens. A teleconverter then seemed like a good idea so I gave it shot. I bought this Bower Teleconverter on Amazon for $126.
